Verbena plant named ‘KLEVE03320’

ABSTRACT

A new and distinct cultivar of  Verbena  plant named ‘KLEVE03320’, characterized by its compact, upright, outwardly spreading and mounded plant habit; freely branching habit; dense and bushy growth habit; dark green-colored leaves; white-colored flowers with flowers held above and beyond the foliage; and resistance to Powdery Mildew.

Botanical classification/cultivar designation: Verbena hybrida cultivar KLEVE03320.

BACKGROUND OF THE INVENTION

The present Invention relates to a new and distinct cultivar of Verbena plant, botanically known as Verbena hybrida, and hereinafter referred to by the name ‘KLEVE03320’.

The new Verbena is a product of a planned breeding program conducted by the Inventor in Camden, New South Wales, Australia. The objective of the breeding program is to develop new compact Verbena cultivars with large flowers and resistance to Powdery Mildew.

The new Verbena originated from a cross-pollination made by the Inventor in 2000 of a proprietary Verbena hybrida selection identified as 00.40.1, not patented, as the female, or seed, parent with a proprietary selection of Verbena hybrida identified as code number 00.38.2, not patented, as the male, or pollen, parent. The cultivar KLEVE03320 was discovered and selected by the Inventor as a flowering plant within the progeny from this cross-pollination in a controlled environment in Camden, New South Wales, Australia in 2001.

Asexual reproduction of the new cultivar by terminal cuttings in a controlled environment in Camden, New South Wales, Australia since 2001, has shown that the unique features of this new Verbena are stable and reproduced true to type in successive generations of asexual reproduction.

SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘KLEVE03320’. These characteristics in combination distinguish ‘KLEVE03320’ as a new and distinct cultivar:

-   -   1. Compact, upright, outwardly spreading and mounded plant         habit.     -   2. Freely branching habit; dense and bushy growth habit.     -   3. Dark green-colored leaves.     -   4. White-colored flowers with flowers held above and beyond the         foliage.     -   5. Resistant to Powdery Mildew.

Plants of the new Verbena differ primarily from plants of the parents in plant habit and flower coloration.

Plants of the new Verbena can be compared to plants of the cultivar Versalena White, not patented. In side-by-side comparisons conducted in Camden, New South Wales, Australia, plants of the new Verbena had larger flowers and inflorescences than plants of the cultivar Versalena White. In addition, plants of the new Verbena and the cultivar Versalena White differed in leaf shape.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying colored photograph illustrates the overall appearance of the new cultivar, showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photograph may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Verbena. The photograph comprises a side perspective view of a typical flowering plant of ‘KLEVE03320’ grown in a container.

DETAILED BOTANICAL DESCRIPTION

The cultivar KLEVE03320 has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature and light intensity without, however, any variance in genotype. The aforementioned photographs and following observations and measurements describe plants grown in Stuttgart, Germany, under commercial practice during the spring in a glass-covered greenhouse with day temperatures about 18 to 22° C., night temperatures about 15 to 18° C. and light levels about 20,000 to 55,000 lux. Cuttings were planted in 12-cm containers and grown for about five months. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 1995 Edition, except where general terms of ordinary dictionary significance are used.
